DISSONANCE AND CONSONANCE 



97 



tones are either in cadence or repose we proceed from 

 tone to tone in four ways as follows : — 



1. From cadence to repose = resolution. 



2. From repose to cadence = progression. 



3. From cadence to cadence = progression. 



4. From repose to repose = progression. 



These four species of steps appear in the next exam- 

 ple: cad. and rep. indicate respectively cadence-tone 

 and repose-tone : the slurs indicate resolutions, and all 

 the other steps are progressions.

In the following ascending and descending scales 

 each progression and resolution is marked pro. and 

 res. respectively. There are two rising cadences or 

 resolutions in ascending and three falling cadences or 

 resolutions in descending. The step from fa up to
